NOTE:

The forward sensor (1) is known to the powertrain control module (PCM) as knock sensor 1. The rear sensor (3) is known to the PCM as knock sensor 2.

Thoroughly clean the knock sensor mounting holes.
NOTE:
Over or under tightening the sensor mounting bolts will affect knock sensor performance, possibly causing improper spark control. Always use the specified torque when installing the knock sensors. The torque specification for the knock sensor bolt is less than the typical 8 mm bolt.

NOTE:
There may be a foam strip on the bolt threads. This foam is used only to retain the bolts to the sensors for plant assembly. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
Install knock sensor 1 (1) or knock sensor 2 (3) with mounting bolt (2). Tighten the mounting bolt to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
Connect the electrical connector (4).
Install the oil filter housing, upper and lower intake manifolds and air cleaner housing assembly. Refer to HOUSING, OIL FILTER, INSTALLATION .
If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level. Refer to OIL, STANDARD PROCEDURE .
Connect the negative battery cable and tighten nut to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
Fill the cooling system. Refer to STANDARD PROCEDURE .
Operate the engine until it reaches normal operating temperature. Check cooling system for correct fluid level. Refer to STANDARD PROCEDURE .
